BLE receiver for specific beacon

[Vishwas Jain]

If there are multiple beacons, let's say B1,B2,B3,B4,B5 and a BLE receiver. I want receiver to only wake up from sleep mode when B1 transmits(long broadcast interval) and do nothing when other beacons transmit(small broadcast interval). If I put receiver in sleep mode and wake it up by radio interrupt, It will wake up on every reception of data of every beacon.(no meaning of sleep mode then.)

If my understanding stated above is correct, what can I do to achieve this? Is there any feature I can use of nRF52 series chip?

The only way to distinguish the various beacons would be from some identifier (eg, MAC address) contained within the message.

Clearly, that means that you have to wake the receiver in order to receive the message!

This is unavoidable.

Yes, that MAC address I can verify but the consequence is that I have to wake up the MCU. Thanks anyway!
